# A student is designing an experiment to find the spring constant \( k \) of a spring using only a set of known masses and a stopwatch. Which procedure would work?

A student is designing an experiment to find the spring constant \( k \) of a spring using only a set of known masses and a stopwatch. Which procedure would work?

- **A.** Hang a known mass from the spring and measure its maximum speed using the stopwatch to time its passage through equilibrium.
- **B.** Hang a known mass from the spring, measure the amount it stretches, and use Hooke’s Law \( F = kx \).
- **C.** Attach a known mass to the spring on a frictionless surface, pull it back a set distance, and measure the time it takes to stop.
- **D.** Hang a known mass from the spring, measure the period of oscillation, and use the formula \( T_s = 2\pi \sqrt{ m/k } \).
